Quizplus · Accepted Answer

The electronic configuration of Argon, with atomic number 18, can be determined by adding electrons to the configuration of Neon, which has atomic number 10. Argon has 8 additional electrons, and these can be added to the next available energy levels and sublevels. The correct electronic configuration is 1s2 2s2 2p6 3s2 3p6, which is equivalent to 1s²2s²3s²3p⁶. Therefore, the correct answer is choice C.
